Can coaches "buy" a player's way back in to the game

[BigT]

My question on this is how much blood on the uniform do you allow? A speck of blood ok? Quarter sized stain on the uniform ok? A fist sized spot? I had a kid in a AAU game that had a fist sized blood stain on his jersey.

I remember reading here years ago that no blood should be on the jersey. I wanted to ask you vets where you draw the line.

By the above mentioned rules I can't be clear.
